As an umpire, all I can say is ...
See you in 2021!
People who think these things are going to work are the same ones who think schools can keep kids 6 feet apart (and that there is enough room in the classroom to do that).
I definitely feel bad for the umpires that have to work with this. I can see half of the coaches/players/fans expecting the umpire to enforce every thing listed on the chart. And the other half complaining about it the entire time. In either case, the umpires are the ones that will hear most of the complaints.
